graphs.graphs_floyd_warshall.floyd_warshall(graph, v)¶

Parameters:

• graph (List[List[float]]) – 2D array calculated from weight[edge[i, j]]

• v (int) – number of vertices

Returns:

shortest distance between all vertex pairs

distance[u][v] will contain the shortest distance from vertex u to v.

1. For all edges from v to n, distance[i][j] = weight(edge(i, j)). 3. The algorithm then performs distance[i][j] = min(distance[i][j], distance[i][k] +

distance[k][j]) for each possible pair i, j of vertices.

1. The above is repeated for each vertex k in the graph.

2. Whenever distance[i][j] is given a new minimum value, next vertex[i][j] is

   updated to the next vertex[i][k].
